Abstract

Cette invention se rapporte à un dispositif filtre à fort gradient de densité, qui est capable de filtrer efficacement un fluide contenant une répartition de particules comprise entre 25 microns environ et 0,2 micron environ à une vitesse de fluide d'au moins 100 cm/hr environ et avec une perméabilité hydraulique initiale supérieure à 10 cm/h/psi environ. Ce dispositif filtre à fort gradient de densité comprend plusieurs couches d'un matériau filtrant, ayant chacune des propriétés de retenue de particules prédéterminées spécifiques. Dans un mode de réalisation de cette invention, ce dispositif filtre à fort gradient de densité utilise comme élément de filtre primaire un matériau à base de fibres de cellulose fibrillées lâches. Dans un aspect de cette invention, ce dispositif filtre à fort gradient de densité est utilisé soit pour la clarification secondaire de fluides biopharmaceutiques contenant des protéines cultivées ou fermentées de production industrielle soit pour la clarification primaire de volumes pré-industriels de ces fluides.
